EMERGENCY OVERVIEW
Appearance: white crystalline powder.
Caution! May cause eye, skin, and respiratory
tract irritation. May cause reproductive and fetal effects.
Target Organs: Thyroid.
Potential Health Effects
Eye:
Causes mild eye irritation.
Skin:
May cause skin irritation. May be harmful if absorbed through the
skin. May cause allergic sensitization in certain individuals.
Ingestion:
May cause irritation of the digestive tract. May be harmful if
swallowed.
Inhalation:
May cause respiratory tract irritation. May be harmful if inhaled.
May cause respiratory sensitization.
Chronic:
May cause reproductive and fetal effects. May interfere with iodine
uptake of the thyroid gland and enlarge it. Some references (e.g.
Dreisbach's Handbook) say that iodine and iodine compounds are
potent sensitizers and that repeated contact may cause sensitivity
dermatitis, laryngeal edema, serum sickness with lymph node
enlargement, and joint pain and swelling.

Section 4 - First Aid Measures
|
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Immediately flush skin with plenty of water for at least 15 minutes
while removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists.
Ingestion:
Get medical aid immediately. Do NOT induce vomiting. If conscious
and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid if cough or other symptoms appear.
Notes to Physician:
Treat symptomatically and supportively.
